LabOne Q streamlines and automates time-consuming tasks such as optimizing instrument settings, generating and uploading waveforms, and synchronizing pulses between multiple instruments. Even with this control and measurement automation, users still have complete low-level access to the instruments. Setup details and instrument settings are accessible through a single line of code. LabOne Q also provides browser-based tools for visualization of the experimental sequence and pulses before execution, giving a simplified overview of complex experiments, even with hundreds of pulses. Supporting High Duty Cycles LabOne Q enables users to get the most out of their setups by helping them extend the time the experiment is providing results. With an optimal duty cycle a quantum computer spends the highest possible computing time on the quantum processing unit. LabOne Q supports the user to maximize computational duty cycles by minimizing communication overhead, optimizing control instructions, pipelining and queuing experiments with a separation in offline and online functionality, and with the interfaces for automation. Additionally, experiments have a clear distinction between real-time execution, when the instruments execute instructions and gather data autonomously, and near-time instructions, when communication with an outside process is necessary. For example, when tuning up a quantum gate with optimal control, real-time calibration sequences are interleaved with optimization steps, where intermediate measurement results are used to optimally calibrate the required gate pulse.

QEC research without boundaries Developing decoders to stabilize the quantum processing unit requires a tight integration of quantum and classical computing resources. For fastest progress, quantum R&D needs full flexibility in how these resources are combined. The ZQCS provides real-time compute power with the freedom to use it without bounds. Each shelf hosts a programmable FPGA with direct access to up to 364 channels. Multiple shelves are freely connected in a full-mesh network. A RDMA over Converged Ethernet (RoCE) interface serves as a high-bandwidth, low-latency link to classical computing CPU/GPU resources. Enabling best quantum fidelities The roadmap to fault-tolerant quantum computing depends on boosting quantum fidelities reliably on large chips. With an analog design led by a deep insight into control error and decoherence mechanisms, the ZQCS enables your push for quantum fidelities beyond 5 nines without limits imposed by the control. The ZQCS achieves this with an analog front end based on direct-RF technology in the first Nyquist zone. It offers the optimal balance of signal properties most relevant to qubit control: the highest SNR on the market, low spurs, stable amplitude and phase, low latency. Scalable software stack The upper layers of the quantum stack bears far too many uncertainties that can slow down or even block quantum computing scale-up: performance ceilings, fragile tune-up workflows, and unreliable interfaces. Zurich Instruments' scalable software architecture keeps these risks in check. LabOne Q lets users design complex experiments at the right abstraction: pulse, gate, or workflow. An optimized compiler and runtime map them to hardware with minimal overhead. Proven automation support keeps performance consistent from single chips to large systems.

Supercapacitors, also known as ultracapacitors or electrochemical capacitors, are promising energy storage devices that bridge the gap between electrolytic capacitors and batteries. Thanks to their high power and long lifespan, supercapacitors are widely used in applications ranging from SRAM to high-speed trains. The key to such high performance is often a low equivalent series resistance (ESR), which reduces the energy wasted via Ohmic heating during charging and discharging cycles. Characterization of the supercapacitor impedance at different frequencies is thus important to determine the ESR and other critical device parameters. At low frequencies, such characterization sets a unique measurement challenge that requires an instrument capable of measuring current and voltage directly and of measuring impedance with high accuracy. With the Zurich Instruments MFIA Impedance Analyzer, it is possible to avoid the above drawbacks by measuring supercapacitors over a wide frequency range, from 1 mHz to 5 MHz, with a small AC test signal. In the four-terminal configuration shown in Figure 1, voltage and current on the device are monitored simultaneously and can be displayed together with calculated impedance parameters in the Sweeper module of the LabOne instrument control software. Switching visualization between Bode and Nyquist plots (see Figure 2) helps to determine other useful parameters in addition to the device's capacitance: these include the ESR, the charge transfer resistance and the Warburg elements with their corresponding frequencies. The ESR is an indicator of the 'health status' of the device as a whole. The charge transfer resistance and the Warburg elements relate to the interface between the electrode and the electrolyte, and are especially relevant to electrochemists who study the device's materials on the microscale. Thanks to the time-domain LabOne Plotter module (see Figure 3) and the configurable LabOne APIs, these parameters can be swiftly streamed to the computer and monitored over the device's lifespan. - Minimize the measurement time by probing two frequencies simultaneously, or by recording all relevant impedance parameters in a single sweep. - Automate your measurements easily and record test parameters as a function of frequency, test signal amplitude and bias offset with the LabOne software and its APIs.

New instruments can be added by plugging one cable without rework of the existing system. Simplified feedback programming The QCCS comes with the LabOne Q software interface that lets users control feedback operations on the system level. LabOne Q translates a user’s high-level sequence into real-time instructions for all components of the QCCS so they can operate in sync, with QHub at the center. A Python API gives users the full flexibility to integrate QHub into their own software. High-fidelity feedback operations Due to the star topology of the QCCS architecture, QHub is able to evaluate the global state of all the qubits that it controls. This enables feedback methods that require global knowledge of the system state, such as Quantum Error Correction. The low-latency global feedback is complemented with local feedback operations inside the SHFQC Qubit Controller with further reduced latency.The powerful FPGA core of QHub enables the user to create advanced closed-loop feedback algorithms, while achieving a low and deterministic latency. Reliable synchronization The ZSync interface distributes all clocks and timing signals needed to synchronize the system. Automated calibration procedures make the synchronization stable across reboots and changing environmental conditions. You can count on weeks of operation without the need for delay calibration.
